Aaron T. Rex’s review published on Letterboxd :
Na Hong-jin's follow up to The Chaser tries hard but never reaches the heights of its predecessor. I was really looking forward to it because I absolutely loved The Chaser and luckily there are many similarities. The Yellow Sea is equally grounded in a Korean way and actually turns up the level of violence and blood quite a bit. Maybe even a little too much in fact.
The performances are of course fantastic. Ha Jung-woo is unrecognizable. Had to check before I could be sure he was the same guy who played a serial killer in The Chaser. What is missing though, is emotional connection. That would've lifted the film up to a top score.
